BUILDING BRICK OR BLOCK AND FACING THEREFOR.

SPEGIFI TION formingpa rt of Letters Patent No. 771,520, dated October4, 1904:.

pplication filed November 11, 1903. Serial No. 180,646. (No model.)

To all whom it may 0 rwern':

Be it known that I, TH MAS W. WORRALL, a citizen of the United States,residing at New York, in the comity of New York and State of NewYorkjhave invented certain new and useful Improvements in BuildingBricks or Blocks and Facings Therefor, of which the following i' aspecification, such as will enable those ki e the art to which itappertains to make and the same. v

This invention relates t building bricks or blocks and facings therefor,and particularly to building bricks or blocks made of clay, concrete, orany other suitable material capable of being molded into the desiredform; and the invention consists in bricks or blocks of this class ofnovel form whereby such bricks or blocks may be locked together inlayers and whereby a facing of any suitable material may be securedthereto, a further object being to provide a facing for bricks or blocksof the class specified composed of tiling or similar material moldedinto the required form and adapted to be locked to said bricks orllilocks after they have been placed in the we I The invention fullydisclosed in the 'following specification, of which the accompanyingdrawings form a part, in which the separate parts of my improvement aredesignated by suitable reference characters in each of the views, and inwhich- Figure 1 is a plan view of a brick or block made according to mynvention and showing a part of a facing nnected therewith; Fig. 2,.afront v1 ereof; Fig. 3, a section on the line 0 of Fig. 2 with thefacing removed,

and Fig. 4 an end view of the facing shown in Figs. 1 and 2.

In the practice of my invention I provide a brick or block a, composedof any suitable material capable of being molded into the required form,and this brick or block is provided in the top, side, and end'portionsthereof with vertically-arranged recesses 5, two of which are shown ineach side and one in one end thereof. The recesses Z) extend downwardlyapproximately to the horizontal ccntral plane of the brick or block, andthese recesses are preferably circular in crosssection, and formed inthe sides and ends of the bricks or blocks are vertical slots oropenings 5*, which communicate with the recesses 12 and which are widerat the top than at the bottom, as shown at 6 the top portions of saidslots or openings being equal in width to the diameter of the recesses12, While the bottom portions thereof are less in width or transversesection than the diameter of said recesses.

By means of this construction contiguous bricks placed in a wall may belocked together by means of cement or other keys, the recesses and slotsor openings being so formed in the contiguous bricks that the said slotsor openings will register. The chief object, however, in making the saidbricks or blocks in the mannerdescribed is-to provide meansforsecuringafacing thereto, and in Figs. 1 and 2 of the drawings I haveshown at 0 a facing composed of terra cotta or any other suitablematerial'capable of being molded into the required form, and this facingis provided with one or more keys 0 according to the length of thefacing and the brick or block. The key 0 consists of a spherical knobconnected with the facing c by a neck 0 and in practice the said key orkeys are placed at the longitudif nal center of the facing in the formof construction shown, and all that is necessary to connect the facingwith a brick or block is to hold the facing so that the key or keys maybe forced backwardly into the opening or openingsb in the side or end ofthe brick or block, after which the facing may be lowered and the key orkeys will drop down into the recess or recesses b and the facing will besecurely locked to the brick or block.

If desired, cement may be used between the facing and the brick or blockand also to fill the recess or recesses and the slots or openings Z2 and72 and the facing may thus be securely connected with the brick orblock.

In the form of construction shown the brick or block is provided in oneside or one end with vertically-arranged grooves or recesses (Z, anydesired number of which may be provided and in which cement may beplaced, this cement being placed between the various bricks or blocks ina wall and alsobetween the facing and the various bricks or blocks,

11 these grooves or recesses may be formed all the sides and ends of thebricks or blocks, desired.

It will be apparent that when a wall composed of bricks or blockssimilar to that herein described has been finished the facing or facings0 may be placed in position in the same manner as herein shown anddescribed, and these facings may correspond in dimensions with one ofsaid bricks or blocks, or a single casing may cover several bricks orblocks.

The facing or facings may also be placed in position when the wall isbeing constructed, if desired, and my invention is is no way limited tothe size or dimensions of the bricks or blocks nor the size ordimensions of the facing or facings, and the facing or facings may begiven any desired shape or configuration or ornamentation on their outerside.

The brick or block shown in the drawings is provided with the recessesI) and the corresponding slots or openings 6 and b in two sides and oneend thereof; but both ends may be similarly provided, and when thusconstructed all the contiguous bricks or blocks in a single layer may belocked together, and this arrangement also facilitates the placing ofthe bricks or blocks at the corners of a building and the breaking ofjoints in the separate layers; but it will be apparent that for thepurpose of securing the facing or facings to bricks or blocks of thisclass only one side thereof may be provided with the recesses b andslots or openings 6 and b in bricks or blocks not used at the corners ofa building or the corners of a wall, and corner bricks or blocks may bemade so as to fill the requirements in such cases; but where all thebricks or blocks are provided in each side and end with the recesses band side slots or openings 5 and b", communicating therewith,the bricksor blocks -in separate layers may be locked together,

and facing or facings 0 may be applied in the manner described.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A building brick or block the top surface of which is providedadjacent to a side thereof with a vertically-arranged recess whichextends downwardly intoflthe brick or block a predetermined distance,the side of the brick or block being also provided witha.verticallyarranged slot or opening communicating with said recess andwider at the top than at the bottom, and a facing provided with a keycomprising a knob or head connected with said facing by a neck, saidknob or head being adapted to be inserted into said recess through thetop portion of said slot or opening and to be dropped into the bottomportion of said recess, substantially as shown and described. 2. Abuilding brick or block, the top surface of which is provided near thesides and ends thereof with vertically-arranged recesses andvertically-arranged slots or openings formed in the sides and ends andcommunicating with said recesses, said slots or openings being wider atthe top than at the bottom and a facing provided with a key or keyscomprising knobs or heads connected with said facings by necks, saidknobs or heads being adapted to be forced backwardly into said recessesthrough the enlarged upper portions of said slots or openings,substantially as shown and described.

3. Abuilding brick or block, the top surface of which is provided near aside thereof with a vertically-arranged recess, said side being providedwith a vertically-arranged slot or opening communicating therewlth, anda facing provided with a key adapted to be inserted into said recessthrough the top portion of said slot or opening and to drop into thebottom portion of said recess, substantially as shown and described.

4:. A building brick or block and a facing therefor, one of said partsbeing provided in one of the faces thereof and adjacentto another facethereof'with a recess parallel with the last named face and extendingpartially through said part, said last-named face being also providedwith a slot which communicates with said recess throughout its lengthand is of less dimensions in transverse section than said recess exceptat the end thereof adjacent to the first-named face of said part whereit is of the same dimension in transverse section as said recess; andthe other part being provided with a key comprising a knob or headconnected therewith by a neck, said knob or head being adapted to bepassed backwardly 'into said recess through the enlarged end portion ofsaid slot, substantially as shown and described.

In testimony that I claim the foregoing as my invention 1 have signed myname, in presence of the subscribing witnesses, this 9th day ofNovember, 1903.

THOMAS \V. WVORRALL.
